FANUC A06B-0315-B042 Model 10S AC Servo Motor with 2500P Absolute Pulse Coder

This model is commonly identified as A06B-0315-B042#7000. The standard configuration does not include a shaft keyway or holding brake, making the complete nameplate number important when selecting a replacement.

2500P Absolute Position Feedback

The absolute pulse coder provides rotor position and speed feedback to the servo-control system. Absolute-position retention depends on the corresponding CNC or servo-system backup battery, so battery condition and the correct encoder-disconnection procedure should be checked before removing the motor.

10S Feedback Model Identification

Within the related Model 10S family, A06B-0315-B041 is associated with 2000P absolute feedback, A06B-0315-B042 with 2500P absolute feedback and A06B-0315-B043 with 3000P absolute feedback. These motors should not be interchanged solely because the mechanical frame appears similar.

Standard, Keyed and Sealed Versions

The standard #7000 configuration uses a smooth shaft without a keyway. Versions carrying suffixes such as #7008 or #0008 may use a keyed shaft, while #7075 identifies a separately specified sealed/IP67 version. These features must not be assumed for the unsuffixed A06B-0315-B042.

Replacement Compatibility Check

Before ordering, compare the complete FANUC number and suffix on the original nameplate. Confirm the Model 10S requirement, shaft style, brake arrangement, 2500P absolute feedback, connectors, mounting dimensions, compatible servo amplifier and existing CNC parameters.
